The time I accidentally spent a year combatting fraud

The author, Barry, shares the story of his most intense year as a professional developer, where he was hired as the sole developer for a 14-year-old high-end marketplace that was going through a chaotic ownership transition while simultaneously being targeted by fraudsters. He shares the technical challenges they faced, including phishing attacks, fraud, and bugs on both the old Perl site and the new Ruby on Rails site. Barry also provides insights into their problem-solving strategies, including implementing DMARC to combat phishing, building in a way to automatically reverse account takeovers, and “wasting” spammers’ time to decrease their return on investment.
